There are a lot of accurate long barrel pistols for hunting, but most of them are essentially made for a rest.
........and as a Sportsman, you owe it to your quarry to use some kind of rest when using a handgun, regardless of barrel length.
This is a very true statement. Whether your rest is a tree,knee or whatever, a rest should be used. Don't think I've ever shot a deer with a handgun without some kind of rest.
